I had nothing to lose and had it apart. It's the leading (front-side) element which, I thought was the crown portion. The set is air-spaced. They were isolated by a thin "gasket" running between them at the perimeter. And I said old, but not quite that old. (60's vintage Sears Discoverer 6333-A).

Oh, I forgot, he used a singlet objective. Is it really the crown that's chipped? Generally theconcave side of the flint elemenet gets chipped. Also, are the elements cemented? Cement failures can look like chips.Paul----- Original Message ----- From: "Spencer, Darrell" <DSpencer@xxxxxxx>To: <sac-forum@xxxxxxxxxxxxx> Sent: Wednesday, October 15, 2008 7:11 AM Subject: [sac-forum] Looking for a 60mm f15 objective Not sure if folks here are as interested in older refractors as I am, but I have yet another project that's old, complete and in really pristine shape ... except for the crown half of the objective. Clamshell chips all the way around. If it was a 102mm, I wouldn't worry much, but at 60mm, I'm going to try and find a replacement. If anyone happens to have an unused "cell" they'd like to "sell", I'd sure be interested. (D:60, F:900) Thanks, Darrell Spencer
